When Princess Luna demands her sister to give her more control over ponies, or at least some more worshipers, Princess Celestia refuses to give in to her sister's requests, as she believes that her sister may be too powerful after her demands become real in Equestria. With Princess Luna's anger building up, she lets her anger out by dividing Equestria into three parts, and Equestria falls under the same tragedies as the old times, with Princess Celestia almost too weak to help Equestria recover under Princess Luna's infuriated treachery.
